Patent EP-0301305-A2 (EP)
Inventor: MEYER KLAUS-DIETER DIPL-ING
IPC: C02F3/10
Filed: 1988-07-12
Abstract: A carrier matural as a growth area for biomass, in the form of a plate or web, is used, for example, in biological waste water purification plants to increase the purification performance. However, it has only a low degree of mechanical stability, especially when foam material is used. The invention, on the other hand, offers a carrier matural in the form of a plate or web with a high degree of mechanical stability. This is achieved by arranging a carrier plate or web with high tensile strength between at least two plates or webs of foam material.

Abstract: A box for disposing of used injection needles comprising a case (1; 31) having an opening (2; 32) whereinto a tip portion of a syringe (20) is inserted, a movable member (3; 38), and a fixed member (4; 37), both members being arranged in the case (1; 31). A hub (22) of an injection needle (21) inserted through the opening (2; 32) of the case (1; 31) is firmly held by holding portions (5, 9; 44, 45) of movable member (3; 38) and fixed member (4; 37) due to elasticity of the hub (22) itself. The rotation of the syringe (20) causes the injection needle (21) to be removed from the syringe (20), and the removed injection needle (21), which is not pulled out together with the syringe (20) and remained in the holding (5, 9, 44, 45) portions due to holding effect of the holding portions (5, 9; 44, 45), can be dropped into the case (1; 31) by the operation of a rod (7, 34) outside the case (1; 31).

Abstract: The apparatus embodies a sensor containing a chemosensitive sensor material whose electrical resistance or whose permittivity changes on exposure to gases or vapours. According to the invention, a sensor material which consists either of hydrophobic metal complexes or of a mixture of at least one phthalide and at least one acidic compound is used as resistance or dielectric. The ion mobility and/or the ion concentration of these sensor systems changes on exposure to the gases. The change in resistance or capacitance can expediently be converted into a change in frequency using a multivibrator. In this way, a particularly simple and very effective sensor system for gases and vapours is obtained. …<IMAGE>…

Abstract: The introduction equipment consists of an inner sleeve (10), an intermediate sleeve (20) and an outer sleeve (30), which are made of flexible material and surround each other in a coaxial manner. The inner sleeve (10) has a proximal end section (11) with handle (12) and a thickened distal end section (13), which tapers conically towards its free end and bears a proximal outer shoulder (15). The intermediate sleeve (20) has a proximal end section (21) and a distal end section (22), whose outer diameter is at least as great as the outer diameter of the proximal outer shoulder (15) of the distal end section (13) of the inner sleeve (10). The outer sleeve (30) has a proximal end section (31) with handle (32) and seals (34) and a slightly conically tapering distal end section (33) which can be radially elastically expanded, the outer diameter at the free end of the distal end section (33) of the outer sleeve (30) being slightly smaller than or equal to the outer diameter of the end section (13) at its outer shoulder (15). In this arrangement, the cross-section of the introduction equipment increases from the distal end gradually and continuously, which allows the introduction equipment to be inserted without difficulties into the opening of a vessel. The intermediate sleeve (20) prevents the withdrawal of the inner sleeve (10) after the positioning of the introduction equipment, while it slightly widens the distal end section (33) of the outer sleeve (30) and passes through the proximal end section (13) of the inner sleeve (10).

Abstract: The present invention relates to the accessing data in tables and its application to apparatus for providing a communication bridge interconnecting two or more local area networks (LAN). 
     A LAN (1) is connected to another LAN 2 by means of a bridge generally designated by the numeral (3). Input buffers (11, 21) forward packet headers of received data packets through to a routing engine (5). The routing engine (5) contains one or more routing tables each having a plurality of table locations containing table data in the form of station addresses and routing data. The table is accessed by applying a hashing algorithm to a received destination address contained in the data packet to determine the table location and then checking that the station address retrieved from the table location corresponds with the destination address in the received data packet. If the table location is empty or the destination address does not match the station address, the data packet is forwarded to all interconnected LANs. Otherwise, the data packet is forwarded according to the retrieved routing data. Embodiments are described wherein the table locations are over-written by applying the hashing algorithm to the source address of a received data packet and writing in at the resultant table location the source address and routing information of the received data packet. A time stamp can also be written at this time so that obsolete data entries are not employed for routing.
